Simplifying x2 + -14x + 49 = -33 Reorder the terms: 49 + -14x + x2 = -33 Solving 49 + -14x + x2 = -33 Solving for variable 'x'. Reorder the terms: 49 + 33 + -14x + x2 = -33 + 33 Combine like terms: 49 + 33 = 82 82 + -14x + x2 = -33 + 33 Combine like terms: -33 + 33 = 0 82 + -14x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-82' to each side of the equation. 82 + -14x + -82 + x2 = 0 + -82 Reorder the terms: 82 + -82 + -14x + x2 = 0 + -82 Combine like terms: 82 + -82 = 0 0 + -14x + x2 = 0 + -82 -14x + x2 = 0 + -82 Combine like terms: 0 + -82 = -82 -14x + x2 = -82 The x term is -14x. Take half its coefficient (-7). Square it (49) and add it to both sides. Add '49' to each side of the equation. -14x + 49 + x2 = -82 + 49 Reorder the terms: 49 + -14x + x2 = -82 + 49 Combine like terms: -82 + 49 = -33 49 + -14x + x2 = -33 Factor a perfect square on the left side: (x + -7)(x + -7) = -33 Can't calculate square root of the right side. The solution to this equation could not be determined.
